- Renewed November'ZO, 1939 5 Claims.

This invention relates to spinner and twister rings for use with bar andring travelers and to spinning devices including in a novel combinationmy improved spinner and twister ring and a 1 traveler of either the ringor bar type, which traveler may advantageously be formed withring-contacting running surfaces of non-metallic material requiring'nolubrication, such as, for

.example, the travelers of my prior Patent No.

A principal object of this invention is to provide a spinner and twisterring that is adapted for 7 use with either ring type travelers or bartype travelers interchangeably, without requiring any 3 change of oradjustment to the ring, thus saving the labor, time and loss ofproduction which would be involved otherwise to change the rings when achange from either type of traveler to the other becomes necessary or.is desired; in other i words this object of the invention is to providea single unitary spinner and twister ring which is a permanentcombination of ring suited to the ring type travelers and a ring suitedto the bar type traveler.

; Another object of this invention is to provide a spinner and twisterring of the character described which is adapted to contactsubstantially only a single point of a ring traveler, and only a singlepoint on each foot of a bar traveler, when the traveler is runningthereon, and to have the traveler make edgewise contact against thetrack surface of the ring, and thus to lessen friction and to make forsmoother running with less and more uniform tension and permit operationat higher speeds, resulting in faster production, without increase inthe power load.

Another object of this invention is to provide a spinner and twisterring which prevents the track from being contaminated by emulsion, dirtor other foreign matter that may be thrown 01f from the thread duringoperation.

The objects of this invention, accordingly, in clude the provision of aspinner and twister ring which greatly reduces equipment cost for ringsand travelers, produces a saving in operating costs and increases theavailable operating time and production, since less frequent stoppage ofthe spindles isnecessary for replacement, cleaning of rings andtravelers, orlfor leveling, repairs or tying of broken threads, thanheretofore, and produces agreater uniformity in the twist of the yarn,both with ring type travelers and with bar type travelers.

Other objects of this invention will be in part obvious and in partpointed out hereinafter.

In order that a clearer understanding of this invention may be had,attention is hereby directed to the accompanying drawing, forming a partof this application, and illustrating certain possible embodiments ofthis invention, and in 5 which: t

Fig. 1 is an elevation, partly in section, of cer-' tain portions of aspinning device, showing a spinner ring embodying this invention, and aring traveler adapted to the ring;

Fig. 2 is a plan view of the construction shown in Fig. 1;

Fig. 3 is a detail view'of the ring and traveler shown in Fig. 1;

Fig. 4 is a sectional view showing a modified construction of the ringand a bar traveler adapted thereto.

In the drawing the travelers are depicted as in the positions theyassume when running.

Similar reference characters refer to similar 2 parts throughout theseveral views of the drawmg.

Referring to the drawing, the spinner and twister ring, embodying myinvention is shown as shaped toform a depending annular lip I having r asmooth, rounded traveler track surface 2 extended downwardly, andadapted to be engaged with rocking contact by the traveler 3 at point 4or its inner edge portion which has greater curvature than'the curvatureof the nose surface 2. In Fig. 4, showing a bartraveler 5, the curvedcontacting edge portion of-the foot of the traveler is indicated at 6.

As shown in the drawing, the lip l of the ring may comprise the loweredge of an annular flange or wall 1 which is inclined inwardly anddownwardly at a steep angle (52 to the horizontal in the drawing).Flange 1 is supported by an annular wall portion 8 which extendsdownwardly from adjacent the upper edge of flange I at 40 approximatelyright angles thereto and terminates in an annular base portion 9 whichis lower than the lower edge of flange l and is secured to theattachment ring III of the ring assembly, as by being frictionallyengaged against a shoulder I l on ring In and seating on a portion l2 ofthe ring, as shown in Fig. 3. If desired, the meeting faces of theportion 9 of thespinner ring and the shoulder ll of the attachment ringIll may be provided with complementary threads (not shown) and the partsscrewed together. Sufficient space isprovided between the lip I and, theupper surface of the body of ring l0 so that the traveler will runabsolutely freely therebetween. To this end the upper surface of ring lmay be foriiiedto have a hollow or groove ll. An annular vertical wallor flange I5 is provided about the inner edge of ring ill-and extendssumciently high above the level of the traveler track 2 to interceptemulsion or other foreign matter thrown from the thread toward thetrack,-and thus prevents such emulsion, rust, acid and other .foreignmatter from reaching the track, and

keeps the track clear of contamination.

As shown in Fig. 3, the ring traveler is substantially in the shape of aO and embraces the wall I. The lower end It of the traveler extends wellunder the lip I, and its upper end I! hooks over a ridge is,constituting the upper edge of flange I. Thus the traveler cannot bejerked from the ring or fly away therefrom. When the traveler isrunning, its upper portion l1 and its body,

as well as its lower extremity l6, are spaced'from and do not contactany part of the spinner ring, the only point of contact being thecontact mentioned before between the rounded surface. 2 of the lower lipI of the ring and the wider curved surface tof the traveler. This pointof contact is a fulcrum point on which the traveler may rock upwardlyuntil its inner periphery meets the ring flange i at or near the ridgel8, and the traveler may rock downwardly until its end l1 strikes thewall 8. Upper end ll of the traveler is sufliciently short so as not tostrike the flange 8 at any time when the traveler is running.

The thread guide 20 of the traveler is so positioned on the travelerthat when the traveler is running it is approximately in vertical linewith v the contact point between the ring and traveler and is connectedwith the traveler at such a place that the combination of the action ofthe centrifugal force and the pull of the thread 30 maintains thetraveler out of contact with the ring except at the contact or fulcrumpoint, and the f contact at this point will be extremely slight andapproximately frictionless, When the ring traveler is at rest its lowerportion seats in groove M of the ring and end Ii engages ring ridge l8,

thus preventing the traveler from becoming disengaged from or fallingoff the ring flange l and maintaining the traveler upright, facilitatingeasy and smooth pick up and starting with a minimum of friction andstrain.

matter thrown off the thread, which is not the case with the usual priorconstructions.

Similarly, when bar travelers are used with rings embodying my inventioneach end of the traveler has contact with the ring at one point only,whereas in the usual prior constructions the end of the bar travelercontacts the track flange of the ring both at its tip and at anintermediate surface. Thus, with bar travelers, as well as with ringtravelers, 'mymvention reduces the frictional contact between the ringand the travelers and secures the improvements and advantages morespecifically pointed out hereinbefore, as well as other improvements andadaiasyo vantages which will be'understood and appreciated readily bypersons familiar with this art.

Spinner rings and travelers embodying my invention may be made of anysuitable material with the track. surfaces having a hard and smoothfinish; However, the travelers, or at least the contact portionsthereof, are preferably made of fibre or the like, since by the useofsuch materials no lubrication is necessary, and all the disadvantages ofand objectionable features connected with lubrication, are avoided.

As many changes could be made in the above construction, and as manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is to be understood thatall matter contained in the foregoing description or shown in theaccompanying drawing be interpreted as illustrative and not in alimiting sense.
